Patent JP-S6038879-A (JP)
Title: Manufacture of semiconductor device
Inventor: IZAWA RIYUUICHI
IPC: H01L29/78
Filed: 1983-08-12
Abstract: PURPOSE:To enable the restraining of an internal electric field which is enhanced according to miniaturization of a MOS transistor by introducing an impurity element of a small diffusion coefficient at one process of impurity doping in order to reduce the concentration gradually toward a channel of a drain. CONSTITUTION:An impurity of a small diffusion coefficient, e.g. As is used in case of NMOS. When the diffusion layers 32, 33 and 14 having inverse conductive types to that of a substrate 34 are subjected to one ion implantation through a film 31 and an oxide film 15, the concentration reduced gradually toward a channel because the film 31 has a thickness inclination and the diffusion layer 33 has a concentration gradient in a longitudinal direction of the channel of a MOS transistor. Accordingly, the strength of an electric field of a depletion layer region can be reduced without causing the reduction of an effective channel length.

Title: Carbon monoxide sensor
Inventor: SUGANO KOJI
IPC: G01N27/12
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To selectively and safely detect CO gas by disposing a filter absorbing NO, NO2 and SO2 and permitting carbon monoxide to pass to a passage for introducing gas to be detected into a detection element. SOLUTION: The surface of a detection element 1 is covered with a filter housing 12. An opening 13 is provided to the top part of the housing 12 and gas to be detected is introduced from the opening 13 to transmit through filters 7, 8 of a two-layered stucture while diffusing throughout them to arrive at the surface of the element 1. At this time, NO, NO2 and SO2 are adsorbed by activated carbon or reacted with alkali metal carbonate along with moisture contained in the gas to be detected to be reduced in the amt. arriving at the surface of the detection element 1. Contrarily, carbon monoxide is slight in the amt. adsorbed by activated carbon and not reacted with alkali metal carbonate.  Therefore, the influence of NO, NO2, SO2 or the like on the detection element 1 is reduced and the detection sensitivity to carbon monoxide thereof is stabilized and carbon monoxide can be selectively detcted.

Title: Method for treating water flow containing undesirable amount of cyan compound
Inventor: ROBAATO AARU FUREIMU
IPC: B01J31/18
Filed: 1992-06-08
Abstract: A cyanide-containing aqueous stream is treated to reduce the cyanide concentration by oxidation of cyanide using oxygen as the oxidizing agent under mild reaction conditions in the presence of a metal chelate catalyst. Especially effective chelates are metal phthalocyanines, particularly where the metal is vanadium or a member of the iron group metals. The oxidation can be effected homogeneously using water soluble metal chelates, or can be performed heterogeneously, especially in a continuous fashion using a packed bed reactor, by using suitable water-insoluble metal chelates, especially when supported on appropriate carriers.

Abstract: PURPOSE:To form a high-quality thin film even at a stepped sidewall part at a low temperature and homogeneously by repeating the following alternately: a deposition process by decomposing a plasma of a raw-material gas used to deposit a thin film; and a process to preferentially remove a defect part in the film. CONSTITUTION:At a first films-deposition process, a Ta-based raw-material gas is introduced into a raw-material gas introduction port 18 when, e.g. a tantalum oxide thin film is formed, and gases such as N2O, O2 and the like or a mixed gas of them are introduced into a second introduction port 19 from an electrode 15 through a light-source part. In the first process, a raw-material gas or other gases are introduced, a plasma is decomposed, the surface of a substrate is irradiated simultaneously with light from a short-wavelength light source and a film is deposited. At a second defect-removal process, an etching gas or a mixed gas with it is introduced form the gas introduction ports, the substrate and its neighborhood are irradiated with light from a light source 16 and a defect is removed. When the two processes are executed alternately, a dense and good-quality thin film can be deposited and formed at a low temperature without damaging the substrate.
